(54)	Power plant with exhaust gas recirculation system

(57) A power plant (10) is provided and includes a gas turbine engine (20) having a combustor (40) in which compressed gas and fuel are mixed and combusted, first and second supply lines (35,36) respectively coupled to the combustor (40) and respectively configured to supply the compressed gas and the fuel to the combustor (40) and an exhaust gas recirculation (EGR) system (70) to re-circulate exhaust gas produced by the gas turbine engine (20) toward the combustor. The EGR system (70) is coupled to the first and second supply lines (35,36) and configured to combine first and second portions of the re-circulated exhaust gas with the compressed gas and the fuel at the first and second supply lines (35,36), respectively.
